Let's make this birthday one to remember.

90 years old (Born on March 28, 1934)

Happy Birthday, Lester R. Brown! Another year older and still saving the planet—talk about sustainability! Your tireless dedication to environmental awareness has inspired countless people worldwide. With over 50 books under your belt (seriously, do you ever sleep?), you've shown us that protecting our Earth is not just essential but also endlessly fascinating.

From founding the influential Earth Policy Institute to enlightening readers with "Full Planet, Empty Plates," your insights have nourished minds even when plates were emptying globally. Here's hoping this birthday brings as much joy as you've brought clarity on global food scarcity issues—and may all future birthdays be sustainably hilarious too!
